[QUOTE="thor447, post: 3513617, member: 24867"] Pulled from another website, but good info: Acidic water dissolves the tarnish. The tarnish is nothing more than metal oxides. This is how acids dissolve metal. There must be an oxidating agent to oxidize the surface of the metal (or simply regular water and air and a lot of time), and the acid then dissolves the oxidized surface layer, exposing fresh metal to continue the cycle. In the case of tumbling brass, you are just removing the oxide layer with acid, and no oxidizing agent. (If you put lemishine and hydrogen peroxide in your tumbler, you could dissolve your cases away!) The "polish" or smoothness of the finish will be the same in either case. The color is different, because tarnish is darker. [/QUOTE]
